Machine Capability Analysis (MCA) testing helps improve yields and reduce soldering and missing-component defects by improving dispense accuracy. By running a capability test, the basic settings and functions of the dispenser are checked (clamping, sensors, nozzles, camera, robot, etc.) so that the dispenser is once again operating within the manufacturer’s specifications.

Machine capability for an automated dispenser of adhesives or solder pastes is measured by dispensing dots of material onto a patterned glass test plate and then evaluating it in CeTaQ’s CmController5, which measures the positional accuracy of the dots. The glass plate minimizes the dimensional errors associated with an FR-4 board, for accurate, relevant measurements.

The controller measures the positioning accuracy (x,y) of the dispense gantry, and evaluates deposit accuracy as well as diameter consistency. Measurements are calculated, taking into consideration the impact of placement order, type of head, single dot versus double dot, needle configuration and other parameters.

Provides measurement technology for equipment and process capability analysis for dispensers and other production equipment; the data and measurement results obtained provide the base for stable and controlled dispensing and processing. Special vision algorithms, accurate glass plates and components allow for independent measurement of Cp and Cpk indices on production equipment. All brands and models of SMT printers, dispensers, placement and semiconductor machines are validated. Certification reports validate performance. Does not require a controlled cleanroom environment.

‘Plug’n Spray’ spray fluxer is a drop-in replacement for foam, wave and first-generation spray fluxers. Reportedly gives the operator control over critical parameters in the fluxing process to achieve a uniform, well-defined flux deposit and excellent wicking in through-holes. Works with no-clean, alcohol or water-based (VOC-free) flux. Claims to save up to 40% more flux than comparable fluxing systems.

Designed for the specific physical and chemical properties of no-clean flux technology, such as the typical range for surface tension and capillary viscosity of water-based fluxes. Design eliminates over- and under- spraying.

Features an air-driven, high-precision nozzle with an adjustable cone. Has computer-controlled movement, defined spray angle, short distance (30 mm) to the board surface and adjustable pressure setting of the nozzle. Nozzle is mounted on a table that is driven by magnetic force.

The field retrofit system includes a fluxing unit, a control cabinet and an exhaust hood. Generally fits into the position of the fluxer unit of virtually any type of soldering equipment; may also be installed at the input end of a soldering machine.

Tyco Electronics has launched an integrated system to address the Unique Identification Program (UID) recently instituted by the Department of Defense (DOD).
 
The system encompasses all aspects of the UID protocol as defined by the DOD and makes the user fully compliant when using specific printing and verification techniques. Includes the five elements necessary for a thorough UID specific implementation: design, printability, validation, verification (grading) and readability.
 
The PrintEasy label design software is capable of designing and creating a valid UID specific 2-D data matrix mark on labels, rating plates, asset tags and wire markers in addition to regular features like graphics, serialization and bar codes.
 
With the appropriate T Series thermal transfer printer, users can print the 2-D Data Matrix codes created with labeling software on a plethora of materials and identification products.
 
Once printed, users apply the label or wire marker to the package, component, equipment or a wire bundle.
 
The system is complemented by a range of validation imagers and verifiers (including software and precision mounted hardware) for validating, error-proofing and grading of the 2-D Data Matrix codes generated specifically for UID applications. The Verifiers also generate comprehensive electronic report cards comprising the various elements and parameters of a 2-D Data Matrix to further optimize the printing and application process.
